One thought: Democrats are grinding their teeth about all the terrible blood-letting going on amongst them. Republicans are giddy over it. Democrats wonder whether the in-fighting will be productive or just leave a lot of blood on the floor. Will it turn off voters to see the party in such disarray, etc.?

Why does it matter? Who cares if there's a lot of in-fighting? It only matters to political obsessives and insiders who, obviously, are not politically up for grabs anyway.

So let them fight. Or not fight. Get it out of their system. It will all be ancient history by the next election. Doesn't matter a bit.
